T0 all whom it may concern.' y t Be it known that l, JULIAN lAZIENno a citizen of Poland, residing at R-osebank, in the county of Richmond and State of New York, have invented certain new and useful Improvements in Color-Sitting Machines, ot `which the following is a specification.

` This invention is directed to an improvement `in color-sifting machines, wherein the color is worked through a screen or the like to y eliminate impurities car ied bythe pigment.

ln machines of this type, it is important that the screen element be capable otrendy and convenient.removal. from or apl'jlication to the machine, .in `order to provide for a v change of screen when desired; and also that the spreading elements by which the material is spreadover and "forced through the screen,- mustbe capable `oi vconvenient removal tor cleaning and the like, or the substitution of other elements. v t

` The` present invention is directed to` machine oit this character in which the receptacle is formed with an opening oit such size as .to permit the `convenient vremoval therethrough of the screen or spreading elements, together' with means, including a part controlled by the door for said opening, vfor securing the screen inplace in a manner to `permit its ready disconnection; and the mounting of the spreading elements so that they may be conveniently detached when desired for removal.

improved machine.

The invention is illustrated in the aecompanying drawings, in which:

Fig. -i is a section on line l-p-Liot 1.

Fig. `5 a section online 5 5 ot Fig. 3. The improved machine comprises a container 1 preferably Vformed to provide a circular wall 2 and a converging or rounded bottom portion 3, the latte-r having an outlet 4l.. The container 1 is formed to provide a shoulder 5 at the juncture of the wall. 2 and rounded bottom portion, thisshoulder 5 being of appropriate width tor supporting the screen. The container is provided with a removable cover 6 formed tor the reception Otan inlet 7 and centrally provided to permitthe passage therethrough ot a. drive shattyvvhich beyond the cover is provided with a bevel gear `9, adapted to be engaged `by a bevel `pinion 10 mounted on a power may be conveniently removed or inserted.`

Vlhe wall 2 is .provided with` a door 14, swingingly mounted to close the opening 13., the door being appropriately vflanged at 15 and arranged to be secured in closing position by `a clamping latch 16, to secure a Huid tight connection.

The screen 1T is adapted to divide the upper portion oit the container from the rounded bottom, and must be conveniently removable and replaceable, as itis necessary to use screens ot different mesh with different material, andalso necessary to clean a particular screen after continued use. To provide tor this convenient removability ot the screen, the latter is held in position between a metal ring 18 and a frame 19, which respectively overlie and underlie the peripheral edge of the screen, the Jframe having a ring portion resting upon the shoulder 5in the container', when' the .parte areapplied.

The wall 2` is provided at convenient points i sition to exert pressure upon the ring 18 or to release such ring. The door 14 is formed with similar cam projection 241, to` be operated by anouter handle 211, so that after closing the door, said cam 2d may be turned to overlie and bear upon the ring 18, whereby said ring and thereby the screemare held in tired relation on the shoulder 5.

It will be apparent Jfrom'the above that by opening Ythe door, which thereby with-` draws the wedge lug or projection 24; from cooperation with theclamping ring 20, and

'the subsequent turning of thecam members 21, the screen may be convenientlyremoved `torcleaning or for replacement by a screen otditerent character. c

. The pigment is subjected to a spreading and forcing action into cooperation with the screen through the medium ot a spreading element, comprising bar 25, to the oppollO site ends of which are secured brushes or other spreading elements 26. A rod-lille upright 27 projects from the bar 25, being located however, nearer to one end of said bar than the other. The upper portion of this upright is non-circular in cross section, and a sleeve 28 of similar interior form for a portion of its length is slidably mounted upon the upright, and spring pressed in the upward direction through a spring 29'coiled about the upright between the lower end of the sleeve and the bar 25. The upper portion of the sleeve is adapted to slidably lit the lower end of the drive shaft 8, and may have a key connection therewith as at 30 and be further secured by a set screw 3l.

Thus with the sleeve in operative relation to the drive shaft, the spreading elements are rotated coincidently with he movement of such shaft, and by the location of the brushes 26 at different distances from the center of rotation, it is apparent that the full area of the screen is operated upon by comparatively short brushes.

If it is desired to remove the spreading apparatus, which of course would precede the removal of the screen, the set screw 3l is disconnected and the sleeve 28 moved downwardly on the upright 27 against the tension of the spring 29, and held in its lowered position free of the drive shaft by the use of the set screw 3l, as shown in Fig. 2. The spreading apparatus is thus wholly free of connection with the drive shaft and may be conveniently removed through the opening 13. 1t will be noted that the spring 29 exercises considerable pressure upon the bar 25 when the parts are in operative positions, thus causing a uniform pressure to be exerted on the brushes and on the material being operated on.

If desired, and as preferred, the frame 19 may be in the form of cross wires 38 delining a rectangular outline to directly underlie and support the screen i7. This frame provides a support for the intermediate portion of the screen and prevents sagging or distortion of the screen in use.

It is apparent from the above that the spreading apparatus and the screen, either or both, may be conveniently removed from the machine and as conveniently replaced, without loss of time, and without the neces sity of dismantling the machine or holding the machine out of service for any considerable time.

Aside from the details herein specilied, it is understood that the various parts of the apparatus may be constructed in any preferred or usual manner best adapted for the particular use for which it may be designed.
